Answer:

The correct option is A

Explanation:

A base is usually defined as a substance that produces hydroxyl/hydroxide ion (OH-) as the only negative ion when dissolved in water. However, Bronsted Lowry defined a base as a chemical substance that can accept a proton/hydrogen ion. Example of a Bronsted Lowry base is ammonia (NH₃).

Ammonia (NH₃) when dissolved in water (H₂O) forms Ammonium ion (NH₄+) and hydroxide ion.

NH₃ + H₂O ⇔ NH₄⁺ + OH⁻

From the equation above, we can see that ammonia (NH₃) accepts a hydrogen ion to become ammonium ion (NH₄⁺).

The same reaction is begun with an initial concentration of 0.05 M O3 and 0.02 M NO. Under these conditions, the reaction reache

Ivahew [28]

The balanced equation of the reaction is:

O3(g) + NO (g) → O2 (g) + NO2 (g)

Then the ratios of reaction is 1 mol O3 : 1 mol NO : 1 mol O2 : 1 mol NO2

If you have initially 0.05 M of O3 and 0.02 M of NO, the reaction will end when all the NO is consumed.

The by the stoichiometry 0.02 mol of O3 will be consumed in 8 seconds.

And the rate of reaction is change in concetration divided by the time.

The change in concentration in O3 is 0.02 M

Then, the rate respect O3 is 0.02 M / 8 seconds = 0.0025 M/s

Answer:

See Explanation

Explanation:

The equation of the reaction is;

C7H16(g) + 11O2(g) ---->7CO2(g) + 8H2O(g)

1a) Number of moles in 228 g of H2O = 228 g/18 g/mol = 12.67 moles

From the reaction equation;

11 moles of O2 yields 8 moles of H2O

x moles of O2 yields 12.67 moles of H2O

x = 11 * 12.67/8

x = 17.4 moles of O2

Since 1 mole of O2 occupies 22.4 L

17.4 moles of O2 occupies 17.4 moles * 22.4 L/1 mole = 389.76 L

1b) Molar mass of C7H16 = 100 g/mol

Number of moles in 300 g of C7H16 = 300 g/100g/mol = 3 moles

1 mole of C7H16 yields 7 moles of CO2

3 moles of C7H16 yields 3 * 7/1 = 21 moles of CO2

If 1 mole of CO2 occupies 22.4 L

21 moles of CO2 occupies 21 moles * 22.4 L/1 mole = 470.4 L of CO2

2) Number of moles in 202 L of H2 is obtained by;

1 mole of H2 occupies 22.4 L

x moles of H2 occupies 202 L

x = 1 mole * 202 L/22.4 L = 9 moles of H2

From the reaction equation;

3 moles of H2 yields 2 moles of PH3

9 moles of H2 will yield 9 * 2/3 = 6 moles of PH3

Mass of 6 moles of PH3 = 6 moles of PH3 * 34 g/mol = 204 g of PH3

P 4 + 5O 2 P 4 O 10 , 1.5 moles of product was made in 30 seconds. What is the rate of reaction? 0.011 g/min 210 g/min 380 g/min

Airida [17]

Answer: 850.0 g/min.

Explanation:

The rate of the reaction = (ΔC/Δt) where,

ΔC is the change in concentration of reactants or products.

Δt is the change in time of the reaction proceeding.

The rate is needed to be calculated in (g/min).

We need to calculate the amount of the product in (g) via using the relation (n = mass / molar mass).

mass (g) = n x molar mass,

n = 1.5 moles and molar mass of P₄O₁₀ = 283.88 g/mol.

m = 1.5 x 283.88 = 425.82 g.

ΔC = 425.82 g and Δt = 30 s / 60 = 0.5 min.

The rate of the reaction = ΔC / Δt = (425.82 g / 0.5 min) = 851.64 g/min.

can be approximated to 850.0 g/min.
